Extraction of natural pigments from Mediterranean environments plants

This article it’s a scientific experiment conducted to extract natural pigments from various plant materials, including chamomile, poppy, common wild madder, holm oak, walnut, and Aleppo pine. The researchers utilized different extraction methods, reagents, and temperatures to obtain colour pigments from these plants. The study aimed to analyze the optical properties and colour characteristics of the extracted pigments. The results indicated that different extraction conditions led to varying colours and intensities. Chamomile extracts showed yellow tones, with significant differences based on extraction methods. Poppy extracts exhibited red and purple shades, influenced by pH levels. Common wild madder samples displayed yellowish to bluish tones, depending on the reagent used. Holm oak extracts showed weak coloration, with slight brownish tinges. Walnut extracts displayed brown tones, while Aleppo pine extracts exhibited brown shades with differences in intensity based on pH levels. Chicory extracts showed green to purple tones, varying with different reagents. The study involved a thorough analysis of the colorimetric properties, including clarity, hue, and saturation, of the extracted pigments under different conditions. Statistical analyses were performed to compare the effects of reagents, temperatures, and plant sources on the colour properties. The findings demonstrated significant differences in colour attributes based on these factors. The importance of the use of natural colorants is also recalled., emphasizing their eco-friendly nature and reduced environmental impact compared to synthetic colorants. The study's results contribute valuable information on the extraction and characterization of natural pigments from diverse plant sources, providing insights for potential applications in textiles and other industries. • Ethnobotanical Uses. • Pigment Compounds. • Natural vs. Synthetic Dyes. • Optimize extraction protocols for natural dyes.
